Population justification: The global population size has not been quantified, but the species is described as common in Nepal, Bhutan, Myanmar and China and uncommon to common in India (del Hoyo et al. 2007).
Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction and fragmentation.
